仪表阀门壳体强度试验和阀泄漏量试验的计算

Shell Strength Test and Calculation of Valve Leakage Test

在炼油及化工装置施工过程中,根据SH/T3521石油化工仪表工程施工技术规范和SH/T3543石油化工建设工程项目施工过程技术文件规定,需要对仪表阀门进行壳体强度试验及泄漏量试验。虽然在石油化工仪表施工规范中都有对此部分的描述,但是所讲述的内容并不是非常的详细,所以实际工作中,大家对此部分并没有一个很清晰的认知,对壳体试压及泄漏量试验、公称压力、工作压力、设计压力容易产生不理解的地方,甚至出现好多错误。文章将对此部分内容进行详细的描述及扩充,让大家对此部分有一个清晰的认识。

In the process of oil refining and chemical plant construction, according to SH/T3521 petroleum chemical engineering construction technical specifications and SH/T3543 petrochemical construction project construction process technical documents, the strength test and leakage test of the instrument valve are required. Although there is a description of this part in the petroleum and chemical engineering code, so in practical work, we don＇t have a very clear understanding of this part, we misunderstand about the shell test pressure and leakage test, nominal pressure, work pressure, design pressure. The article will describe and expand the content of this part in detail, let us have a clear understanding of this part.
